How can i make this code to run faster

hi,

I have a csv with around 2 lakhs url to download images from them.I am reading a csv and downloading images:

below is my code:

from bs4 import BeautifulSoup
import requests
import csv
import urllib.request
import os
final_data = []

def get(url, values):
    res = requests.get(url, data=values)
    d = res.status_code
    if d!=200:
        print("Invalid Link")
    else:
        print("Valid link")
    data = res.text
    return data

def readfile():
    with open("./plans.csv", "r") as csvfile:
        reader = csv.reader(csvfile)
        next(reader)
        for row in reader:
            lists = row[0]
            ind = row[1]+".jpg"
            mj = os.path.abspath(ind)
            d = requests.get(lists)
            sublist = []
            try:
                d = urllib.request.urlretrieve(lists, ind)
                sublist.append(mj)
                sublist.append(lists)
            except Exception as e:
                sublist.append(mj)
                sublist.append(e)
            final_data.append(sublist)
    return final_data

def writefiles(alldata, filename):
    with open ("./"+ filename, "w") as csvfile:
        csvfile = csv.writer(csvfile, delimiter=",")
        csvfile.writerow("")
        for i in range(0, len(alldata)):
            csvfile.writerow(alldata[i])

def main():
    readfile()
    writefiles(final_data, "downloads.csv")
main()
 

It is downloading images , but how can i make this code to run fast, like more fast.

any examples or alteration in code is appreciable . Please help
